●Large display is adopted for HD323 (Display size : 50 x 25mm, 49% larger than HD320)
●Mask function
Unnecessary signal can be eliminated from the received signal by manually.
Echo signal from existing structure positioned between sensor and target cause interference. Mask function removes these unnecessary echo effectively.
